INFORMIX 7.1 Include directive in UNIXWARE environment

I have protocol.h file, which supposed to be used from other C-sources as include file. This file contains #include and #define directives and also "typedef enum" statements. I would like to include this file with INFORMIX $include directive: $begin declare section; $include "protocol.h"; $end declare section; But ESQL/C compiler gives me a lot of errors like this: esqlc: "protocol.h", line 6: Error -33051: Syntax error on identifier or symbol '#'. esqlc: "protocol.h", line 116: Error -33200: Invalid statement on symbol 'enum'. esqlc: "protocol.h", line 117: Error -33051: Syntax error on identifier or symbol '{'. ... Does it mean, that I should create another .h file, specific for ESQL/C, which does not contain any #-directives or enum statements? Or I'm just doing something wrong? If somebody can help with this, thank you in advance. Vicky Khodorkovsky Victoria.Khodorkovsky@SiemensRolm.com victoria@clipper.robadome.com khodor@best.com USA, California
